Good one :D
Certainly riled me up at times, but all in all, I enjoyed reading it.

I especially loved the heroine for being quite stubborn and sure in her own ways when the hero came back after not contacting her in any way. I loved that she wouldn't trust him so easily.
But then I was also disappointed in her 'cause she fell for a complete rogue and a guy who has never really regarded her when she was younger. I mean, she didn't really 'fall' for him but yet, she put up with him. Didn't get that.

Other than that, the writing style was good. There were hardly any errors.
The plot was interesting. I loved that we saw them when they were younger. Plus, we get a glimpse at their future together.
There were some twists and turns that I didn't expect. And our heroine once receives shocking news. That was really hardcore.

MCs?
Their chemistry was pretty cool. Plus, we can see how their relationship develops.
